In some embodiments, the protection layer 130 e of the integrated circuit component 130 and the protection layer 132 e of the integrated circuit component 132 are exposed by the insulating encapsulation 140. In some embodiments, the insulating encapsulation 140 at least fills the gaps between the integrated circuit component 130 and the integrated circuit component 132 and between the connecting film DA1 and the connecting film DA2. In certain embodiments, a sidewall 130S of the integrated circuit component 130 and a sidewall 132S of the integrated circuit component 132 are covered by the insulating encapsulation 140. In certain embodiments, a sidewall of the connecting film DA1 and a sidewall of the connecting film DA2 are covered by the insulating encapsulation 140.

In some embodiments, the insulating encapsulation 140 includes a glue or a glue material, and the insulating encapsulation 140 is formed by glue dispensing. In some embodiments, the insulating encapsulation 140 includes an insulator material (such as epoxy-based polymer or the like), an insulator material having fillers (such as silica, alumina, or the like), or the like. Due to the insulating encapsulation 140, the adhesion degrees of the integrated circuit component 130 and the integrated circuit component 132 to the buffer layer 116 are further enhanced.

Referring to FIG. 3, an insulating encapsulation 150 is formed over the carrier 112 by over-molding the insulating encapsulation 140, the integrated circuit component 130 and the integrated circuit component 132 with an insulating material (not shown) and planarizing the insulating material, the insulating encapsulation 140, the integrated circuit component 130 and the integrated circuit component 132 (also see FIG. 10, step S200). As shown in FIG. 3, in some embodiments, after the planarizing step, the connecting pillars 130 d of the integrated circuit component 130 is exposed by the protection layer 130 e, the connecting pillars 132 d of the integrated circuit component 132 is exposed by the protection layer 132 e. In some embodiments, top surfaces of the integrated circuit component 130 and the integrated circuit component 132 are exposed by the insulating encapsulation 140 and the insulating encapsulation 150.

As shown in FIG. 3, in some embodiments, the insulating encapsulation 140 has a top surface 140 a, a bottom surface 140 b opposite to the top surface 140 a and a sidewall 140S connecting the top surface 140 a and the bottom surface 140 b, where the top surface 140 a is coplanar with top surfaces of the connecting pillars 130 d and the protection layer 130 e of the integrated circuit component 130 and top surfaces of the connecting pillars 132 d and the protection layer 132 e of the integrated circuit component 132. In other words, the connecting pillars 130 d and the protection layer 130 e of the integrated circuit component 130 and the connecting pillars 132 d and the protection layer 132 e of the integrated circuit component 132 are accessibly exposed by the insulating encapsulation 140.

In some embodiments, an area of the top surface 140 a is small than an area of the bottom surface 140 b in a vertical projection on the buffer layer 116. In one embodiment, along the horizontal direction X on the top surface 140 a of the insulating encapsulation 140, a lateral distance W1 measured from the sidewall 140S of the insulating encapsulation 140 to the sidewall 130S of the integrated circuit component 130 or from the sidewall 140S of the insulating encapsulation 140 to the sidewall 132S of the integrated circuit component 132 is approximately ranging from 2 μm to 20 μm, however the disclosure is not limited thereto. In an alternative embodiment, the lateral distance W1 is approximately ranging from 5 μm to 300 μm. In an alternative embodiment, the lateral distance W1 is approximately above 300 μm.

On the other hand, in one embodiment, along the horizontal direction X on the bottom surface 140 b of the insulating encapsulation 140, a lateral distance W2 measured from the sidewall 140S of the insulating encapsulation 140 to the sidewall 130S of the integrated circuit component 130 or from the sidewall 140S of the insulating encapsulation 140 to the sidewall 132S of the integrated circuit component 132 is approximately ranging from 10 μm to 100 μm, however the disclosure is not limited thereto. In an alternative embodiment, the lateral distance W2 is approximately ranging from 100 μm to 500 μm. In an alternative embodiment, the lateral distance W2 is approximately above 500 μm. In addition, along the vertical direction Y, a thickness of insulating encapsulation 140 is greater than a thickness of the integrated circuit component 130 or/and a thickness of the integrated circuit component 132.

In certain embodiments, the sidewall 140S and the bottom surface 140 b of the insulating encapsulation 140 constitute an angle θ1, where the angle θ1 is an acute angle. In one embodiment, a range of the angle θ1 is about from 0.5° to 30°. In an alternative embodiment, the range of the angle θ1 is about from 30° to 60°. In an alternative embodiment, the range of the angle θ1 is about from 60° to 85°. The disclosure is not limited thereto.

Continued on FIG. 3, in some embodiments, the sidewall 130S of the integrated circuit component 130 and the sidewall 132S of the integrated circuit component 132 are covered by the insulating encapsulation 140, the sidewall 140S of the insulating encapsulation 140 is covered by the insulating encapsulation 150, and the integrated circuit component 130 and the integrated circuit component 132 are separated from the insulating encapsulation 150 by the insulating encapsulation 140. That is, for example, the insulating encapsulation 140 is sandwiched between the integrated circuit component 130 and the insulating encapsulation 150 and between the integrated circuit component 132 and the insulating encapsulation 150. In other words, the sidewall 130S of the integrated circuit component 130 and the sidewall 132S of the integrated circuit component 132 are free of the insulating encapsulation 150. In the disclosure, the material of the insulating encapsulation 140 is different from the material of the insulating encapsulation 150. That is, the sidewall 140S of the insulating encapsulation 140 is referred as an interface of the insulating encapsulation 140 and the insulating encapsulation 150, where the interface is clearly shown in FIG. 3.

In some embodiments, the insulating encapsulation 140 may differ from the insulating encapsulation 150 in modulus, CTE, and thermal conductivity.

In certain embodiments, there exists fillers in the insulating encapsulation 150 for advanced packaging, where the modulus of the insulating encapsulation 150 may approximately range from about 5 GPa to about 30 GPa, the CTE of the insulating encapsulation 150 may approximately range from about 5 ppm/K to about 20 ppm/K (below a glass transition temperature (Tg) of the insulating encapsulation 150), and the thermal conductivity of the insulating encapsulation 150 may approximately range from about 1 W/mK to about 20 W/mK. In an alternative embodiment of having fillers in the insulating encapsulation 150, the modulus of the insulating encapsulation 150 may be approximately greater than 30 GPa, the CTE of the insulating encapsulation 150 may be approximately greater than 20 ppm/K (below the Tg of the insulating encapsulation 150), and the thermal conductivity of the insulating encapsulation 150 may be approximately greater than 20 W/mK.

On the other hand, the insulating encapsulation 140, for example, does not necessarily bear these criteria in the advanced packaging; and that is, there may not be fillers in the insulating encapsulation 140, where the modulus of the insulating encapsulation 140 may approximately range from about 1 GPa to about 10 GPa, the CTE of the insulating encapsulation 140 may approximately range from about 20 ppm/K to about 60 ppm/K (below a Tg of the insulating encapsulation 140), and the thermal conductivity of the insulating encapsulation 140 may approximately range from about 0.1 W/mK to about 5 W/mK. In an alternative embodiment of having no filler in the insulating encapsulation 140, the modulus of the insulating encapsulation 140 may approximately range from about 1 GPa to about 10 GPa, the CTE of the insulating encapsulation 140 may be approximately greater than 60 ppm/K (below the Tg of the insulating encapsulation 140), and the thermal conductivity of the insulating encapsulation 140 may approximately range from about 0.1 W/mK to about 5 W/mK.

As shown in FIG. 3, in some embodiments, a top surface 150 a of the insulating encapsulation 150 is substantially levelled with and coplanar to the top surface 140 a of the insulating encapsulation 140, the top surfaces of the connecting pillars 130 d and the protection layer 130 e of the integrated circuit component 130 and the top surfaces of the connecting pillars 132 d and the protection layer 132 e of the integrated circuit component 132. In other words, the top surface 140 a of the insulating encapsulation 140, the connecting pillars 130 d and the protection layer 130 e of the integrated circuit component 130 and the connecting pillars 132 d and the protection layer 132 e of the integrated circuit component 132 are accessibly exposed by the insulating encapsulation 150. On the other hand, a bottom surface 150 b of the insulating encapsulation 150 is substantially levelled with and coplanar to the bottom surface 140 b of the insulating encapsulation 140.

In one embodiment, along the vertical direction Y, a thickness H2 of the insulating encapsulation 150 may be ranging from 50 μm to 200 μm; however, the disclosure is not limited thereto. In an alternative embodiment, the thickness H2 of the insulating encapsulation 150 may be ranging from 200 μm to 500 μm. In an alternative embodiment, the thickness H2 of the insulating encapsulation 150 may be above 500 μm. In some embodiments, the material of the insulating encapsulation 150 may include epoxy resins, phenolic resins or silicon-containing resins, or any suitable materials; inorganic filler or inorganic compound (e.g. silica, clay, and so on).

Referring to FIG. 4, in some embodiments, a redistribution circuit structure 160 is formed on the carrier 112. In some embodiments, the redistribution circuit structure 160 is a front-side redistribution layer electrically connected to the integrated circuit component 130 and the integrated circuit component 132. In some embodiments, the redistribution circuit structure 160 is formed on the integrated circuit component 130, the integrated circuit component 132, the insulating encapsulation 140 and the insulating encapsulation 150 (also see FIG. 10, step S300), where the redistribution circuit structure 160 is electrically connected to the integrated circuit component 130 and the integrated circuit component 132 by the connecting pillars 130 d and the connecting pillars 132 d, respectively. Through the redistribution circuit structure 160, the integrated circuit component 130 and the integrated circuit component 132 are electrically connected to each other. In other words, the integrated circuit component 130 communicates to the integrated circuit component 132 through the presence of the redistribution circuit structure 160, and vise versa.

The formation of the redistribution circuit structure 160 includes sequentially forming one or more polymer dielectric layers 162 and one or more metallization layers 164 in alternation. In certain embodiments, as shown in FIG. 4, the metallization layers 164 are sandwiched between the polymer dielectric layers 162, where the top surface of the topmost layer of the metallization layers 164 is exposed by the topmost layer of the polymer dielectric layers 162, and the lowest layer of the metallization layers 164 is connected to the connecting pillars 130 d of the integrated circuit component 130 and the connecting pillars 132 d of the integrated circuit component 132.

In some embodiments, the material of the polymer dielectric layers 162 includes polyimide, epoxy resin, acrylic resin, phenol resin, benzocyclobutene (BCB), polybenzooxazole (PBO), or any other suitable polymer-based dielectric material, and the polymer dielectric layers 162 may be formed by deposition. In some embodiments, the material of the metallization layers 164 includes aluminum, titanium, copper, nickel, tungsten, and/or alloys thereof, and the metallization layers 164 may be formed by electroplating or deposition. In certain embodiments, as the underlying insulating encapsulation 140 and insulating encapsulation 150 provide better planarization and evenness, the later-formed redistribution circuit structure 160, especially the metallization layer with thin line width or tight spacing, can be formed with uniform line-widths or even profiles, resulting in improved line/wiring reliability.

Continued on FIG. 4, in some embodiments, a plurality of under-ball metallurgy (UBM) patterns 170 may be disposed on some of the top surface of the topmost layer of the metallization layers 164 exposed by the topmost layer of the polymer dielectric layers 162 for electrically connecting with conductive elements (e.g. conductive balls). As shown in FIG. 4, for example, a plurality of the UBM patterns 170 is formed. In some embodiments, the material of the UBM patterns 170 may include copper, nickel, titanium, tungsten, or alloys thereof or the like, and may be formed by an electroplating process. The shape and number of the UBM patterns 170 is not limited in this disclosure.

In some embodiments, after the redistribution circuit structure 160 is formed, a plurality of conductive elements 180 is formed on the redistribution circuit structure 160, and is electrically connected to the redistribution circuit structure 160 through the UBM patterns 170. In some embodiments, the redistribution circuit structure 160 is located between the integrated circuit component 130 and the conductive elements 180, between the integrated circuit component 132 and the conductive elements 180, between the insulating encapsulation 140 and the conductive elements 180, and between the insulating encapsulation 150 and the conductive elements 180. As shown in FIG. 4, the conductive elements 180 are physically connected to the UBM patterns 170. In some embodiments, the conductive elements 180 are electrically connected to the redistribution circuit structure 160 through the UBM patterns 170. In some embodiments, some of the conductive elements 180 are electrically connected to the integrated circuit component 130 through the UBM patterns 170, the redistribution circuit structure 160, and the connecting pillars 130 d of the integrated circuit component 130. In some embodiments, some of the conductive elements 180 are electrically connected to the integrated circuit component 132 through the UBM patterns 170, the redistribution circuit structure 160, and the connecting pillars 132 d of the integrated circuit component 132.

In some embodiments, the conductive elements 180 may be disposed on the UBM patterns 170 by ball placement process or reflow process. In some embodiments, the conductive elements 180 may be solder balls or ball grid array (BGA) balls.

Referring to FIG. 5, in some embodiments, the carrier 112 is flipped (turned upside down) and then debonded from the buffer layer 116. In some embodiments, the buffer layer 116 is easily separated from the carrier 112 due to the debond layer 114. In some embodiments, the carrier 112 is detached from the buffer layer 116 through a debonding process, where the carrier 112 and the debond layer 114 are removed, and the buffer layer 116 is exposed. During the debonding step, a holding device 50 is adopted to secure the semiconductor package 10 before debonding the carrier 112 and the debond layer 114. As shown in FIG. 5, for example, the holding device 50 may be an adhesive tape, an adhesive carrier or a suction pad.

In some embodiments, the buffer layer 116 remained on the integrated circuit component 130, the integrated circuit component 132, the insulating encapsulation 140 and the insulating encapsulation 150 is served as a protection layer. Alternatively, in some embodiments, the buffer layer 116 may be subsequently removed, and a surface of each of the integrated circuit component 130, the integrated circuit component 132, the insulating encapsulation 140 and the insulating encapsulation 150 is exposed.

Referring to FIG. 6, in some embodiments, the conductive elements 180 are released from the holding device 50 to form the semiconductor package 10. In some embodiments, a dicing process is performed to cut the wafer of a plurality of the semiconductor package 10 into individual and separated semiconductor package 10. In one embodiment, the dicing process is a wafer dicing process including mechanical blade sawing or laser cutting. Up to here, the manufacture of the semiconductor package 10 is completed.
